Have you tried flashing the bios to 3701 through the bios Flashblack method...

I suspect your PSU is failing. Test the system with another PSU if possible.
You've basically already confirmed all your mobo power inputs and GPU power inputs are properly connected - but you should inspect them for loose, dirty, or damaged pins. You can backprobe with a DMM during boot to confirm voltages are not fluctuating under load.
Mobo CR2032 battery might need replacement if it's old. Complete battery failure would cause other issues, but intermittent/weak battery can cause all sorts of strange problems which are difficult to troubleshoot. Worth spending a buck to possibly correct this problem and to certainly rule it out, saves time either way.
It's possible your CPU needs to be remounted, but this would be the last thing I'd check.
You say this problem only occurs about once a week and cannot be reproduced on demand, so there's little immediate urgency ... but a PSU operating out of tolerance does accelerate electrical wear on everything downstream, so I advise confirming/denying if it's your failing hardware component somewhat promptly.

I would check the power supply as suggested. But if that is not the cause, here are definitions of your codes that may offer some clues to the cause of the trouble:
Code 78 is for ACPI module initialization (Advanced Configuration and Power Interface),
Code 68 is for PCI host bridge initialization,
Code 70 is for Southbridge DXE initialization (Southbridge chip is X99, and DXE is the Driver Execution Environment phase of boot).
The Southbridge chip controls some of the PCI Express slots, so it might be meaningful that you get both codes 68 and 70 on a warm reboot.
Maybe codes 68 and 70 point to a corrupted chipset driver? On my R5E/X99 the Windows installed driver version 10.1.1.38 on all PCIE ports. You could try updating the drivers in Device Manager. Hopefully not a failing Southbridge chip.
The PCIE slots controlled by the Southbridge are the gray-black ones (PCIE 2.0 x4_1 and PCIE 2.0 x1_1), and they share bandwidth with the USB3_9 and USB3_10 ports under the Ethernet RJ45 jack on the back panel. So if you have any devices plugged into those PCIE slots or those USB jacks you might try unplugging them and see if your system boots normally. Problem could be a bad piece of hardware or external drive that the BIOS has trouble initializing, or bad drivers for those devices.
Good luck.

Hi
I tried disconnecting everything from USBs, HDDs and all PCI-E devices to no avail, as well as different drivers of Chipset and MEI. I just hope there is nothing wrong with the mobo.
But yesterday I bought a new CMOS battery and reverted back to 3701. Will see if the issue happens again, if it didn't happen for at least two weeks straight I will assume that it is fixed. If it happens again my next bus-stop will be the PSU.
Thanks for the help
I really liked the community here, they know their stuff, very articulate and professional. Thanks again.

I too enjoy the community here and I've learned much. It is a really nice resource. One further thought occurred to me and that is to reset the power connectors to the video card, because you had an ACPI code plus codes for PCI bridge. If you buy a new power supply and that fixes the problem then great! If not, then you have a spare power supply which is always good to have around. Let us know what you find.
BTW, if you need to replace the motherboard, the R5E is still available from Newegg for $340
